1. One of my favorites is the three-instruction forth of the MSDOS Pygmy Forth by Frank Sergeant. He uses a tethered Forth, I believe, a more fully functioning forth on a PC, a serial link to the target, and peek, poke, execute (basic language terminology) on the target, i.e., read, write, and run.

If any or all of those paradigms sound strange to you, don’t worry, we’ll explain each one when appropriate. In this part, we’ll limit ourselves to procedural and stack-oriented for the time being.
This manual is for Gforth (version 0.7.9_20240821, August 21, 2024), a fast and portable implementation of the Standard Forth language. It serves as reference manual, but it also contains an introduction to Forth and a Forth tutorial.
Forth is actually much more powerful than what I’ve taught here (and what I implemented in my interpreter). A true Forth system allows you to modify how the compiler works and create new defining words, allowing you to completely customize your environment and create your own languages within Forth.
The Forth Interpreter. Using Forth's Command Line Interpreter. The most common Forth interface is a command line interpreter. Forth recognises a large number of instructions (called "words"). Here we will look at a small selection of them. The word " + " adds two integers. It is used like this; (Words in Forth are delimited by spaces.)
